Abstract

Disclosed is a method for reducing the malodor associated with disposable absorbent products intended for the absorption of body fluids. The method involves applying to the absorbent product, prior to its use, an effective amount of a surface-active agent having a hydrophilic/lipophilic balance of less than about 12. The surface-active agent is effective to reduce the odor of urine. Also disclosed is a disposable absorbent product intended for the absorption of body fluids, which disposable absorbent product includes an absorbent structure including a water-swellable, generally water-insoluble absorbent material, a covering material, and an effective amount of a surface-active agent having a hydrophilic/lipophilic balance of less than about 12. The surface-active agent is effective to reduce the odor of urine.
